Abstract

The present invention aims to provide an antenna made of a complex structure wherein dielectric components having a low dielectric constant form a periodic lattice with a high-permeability magnetic components so as to increase the gain, efficiency and bandwidth of the antenna, while keeping the antenna size small, which is an advantage in conventional antennas using a dielectric with a high dielectric constant. To this end, the present invention provides an antenna based on a dielectro-magnetic composite structure, comprising: a substrate; and a radiation patch formed over the substrate, wherein the substrate is formed in a composite structure of a dielectric-magnetic periodic lattice.
